This is a modified version of Cyclone103's Chaos Game (http://scratch.mit.edu/projects/Cyclone103/158093)
In this version, you can:
* Drag the corners of the triangle (red, blue, and green)
* Control how far the pen moves on each step (with the SCALE slider)
Try adjusting the slider and moving the corners, click the Green Flag, and observe how the pattern changes.
On each step, the pen randomly chooses one of the three corners, moves a certain percentage of the way towards that corner, and draws a dot. The SCALE slider controls the percentage.
